介质反射膜层

介质反射膜层


介质膜层反射镜可以提供很高的反射率(在设计波长反射率可以超过99.8%),莱普可以根据客户的要求提供中心波长从250nm到2200nm的介质反射镜,在选择合适的介质高反时, 需要考虑到膜层损伤阈值的要求。莱普可以提供HR和PR反射镜。

镀膜类型 性能和应用
高反 介质高反膜层 Provide high reflectance over a broad bandwidth, and is ideal for a tunable laser or in white light applications
部分反射 窄带 Provide 50% reflection and transmission at an angle of 45° incidence for a single wavelength. Perfect for beamsplitters application. Transmission/reflection (T/R) ratio of 20/80, or others for Beamsplitter is available upon request.
宽带 Over a wide bandwidth provides 50% reflection and transmission. LaserStates can also provide coatings with different R/T ratios at and specific angle of incident.
